In normal fetal circulation the path of oxygenated blood returning from the
placenta passes though several fetal shunts. One of these normal fetal
pathways between the aorta and PA can be described as a:
a- L>R shunt termed the PDA
b- R>L shunt termed the PDA
c- L>R shunt termed the foramen ovale
d- R>L shunt termed the foramen ovale
✓ the PA-AO shunt is the PDA and its right to left. When the left heart
pressure begins to exceed the right heart pressure, that such a shunt
would switch to left to right
What is the name of the coronary arteries which normally branch off the Cx
artery towards the apex of the heart?

b- open the mitral valve (diastolic filling)
c- eject blood out of the LV and into the AO (SEP)
d- overcome friction of blood viscosity and muscle compliance
✓ A. One of the chief benefits of IABP is to lower the pressure at which the
aortic valve opens, which decreases pressure work. This pressure work
account for 90% of the work done by the LV
Which of the following is a common result of right sided heart failure?
a- dyspnea
b- pulmonary congestion
